We booked the AH88 trip for July 8 through the Gray Line and were extremely pleased! ATVing was an unforgettable experience: driving through small ponds, lava fields, up and down steep mountains. It is not a trip for those who may be nervous on rough terrain! We had an exceptional guide who made sure we felt comfortable on the straightaways before taking us to the more advanced terrain. In addition, they make sure you are equipped in warm/rainproof attire. It was an unforgettable adventure!
